TO ALL WHOM IT MAY CONCERN.:

Bc it known that I, G. W. Nl Yos'r, of Corry, in the county of Erie, andState of Pennsylvania, have invented a new and improved Mowing-Maehineand Ido herebydeclare that the following is a full, clear, and exactdescription thereof, which will enable others 'skilled in the art tomake and use the same, reference being had to the accompanying drawingsforming a part of this specification, in which- I Figure 1 represents aplan or top view oflmy invention.

,Figure 2 is a side elevation, partly in section, of the same,the planeof section being indicated by the line :r x, Iig.

This invention relates to a new mowing-machine, which is constructedwith a view to siniplicity, compactness, and cheapness. l

The invention consists, first, in the manner of arranging the frame ofthe machine. The sanne is composed 0f a horseshoe-shaped metal bar orplate, to thctwo ends of which the shoe at the inner end of thefinger-har is secured. The main body of the frame is about'on a levelwith the driving-shaft of the machine, while its two ends are bent downto reach1to the shoe, and to be hinged to the finger-bar. The axis ofthe horse-shoe is at right angles to the pole/otl the machine, andparallel with the linger-bar. Across the two arnis of the horse-shoe baris laid a straight bar, the same being secured to the higher part of theframe. The main shaft of the machine has its bearings in the saidstraight bar, and in the centre of the horse-shoe bar, and thedriving-wheel is mounted on this shaft, onlyr one wheel being used. Thedrivcr's seat is secured to the frame on that -side of the pole which isopposite to that to which the nger-bar is secured, andthe weight of thedriver thus balances that of the finger and cutting-bar. Thedriving-wheel is, by suitable gearing, connecte-l with the pitruan.thatgives motion to the cutter-bar. I l

The invention consists, second, in 'a device for raising the finger-barand its appendages over obstructions, said device being composed of acaster-wheel, hung in the end of a bar which is pivoted to the frontpart of the shoe. The wheel fits through a slot in the shoe, and restsupon the ground. The bar to which it is secured is connected with alever, which is within easy reach of the driver, and thus, when thedriver desires to raise the Cutters over obstructions of any kind, hedepresses the end of this lever, thereby, the caster-wheel being thefulcrum, he raises the point at which Vthe bar carrying the caster-wheelis pivoted to the shoe, and consequently the whole shoe, and theinger-bar, and, as the shoe is secured to the lower part of the frame,he also raises the lower part of the frame, bringing the whole frameinto an inclined position. As soon as the lever is again released, theweight ofthe driver and of the-wholeniachine tends to depress themachine, and to return it toits original position,

A represents the frame of my improved mowing-machine. The same consistslof two pieces, a and b. The piece a is a metal bar, shapedvsoinewhatlike a horse-shoe, with the ends bent down, and the upper part at alev'el, The piece is a .straight metal or other bar, laid across -tbctwo arms of the horse-shoe, at the upper portion of the same, as shown.v

B is the main shaft of the machine, having its bearings in the bars aand as shown.

C is the main drivingwheel ofthe machine,` mounted on the shaft, asshown.

D is the pole, secured to the frame, so-as to lbe parallel with the barb of the same.

To the lower ends of the bar t is secured a shoe, E, and to the rear endof the bar a is hinged the ngerbar F, of suitable construction, carryinga suitable cutterbar, Gr, as shown. e

By means of suitable gear-wheels, c c, or other equivalent devices,motion is imparted from the driving-shaft B to an axle, ai', to whichthe pitmau-'wheel e is secured, the rod ZL connecting the wheel e withthe cutter-bar Gf,

L and imparting motion to the latter.

His the'drivers seat, secured uponi'avstand'ard orfstandar'ds,gfprjecting'froui therounded prt of the horse-shoe bar a, so as to beopposite to the finger-bar, asshoivn.4

I is a. bar, pivoted to thefront part of the shoe E; at 'or near thejunction ofthe same with the front arm of a. The r-ear end ofthe bar Icarries a. easter-wheel, J, which fits through a slot in the shoe E, andwhich rests upon the ground, as shown in g. 2. l The f ront end ofthebar I is connected with a lever, f, which is within reach of the driverwhen the same is on the sweat H, as shown. I* Y By pulling the end oftheleverf'towalrds the seat, the frontend of the bnr I will be raised,therebyvraising the shoe E, and the finger-bar audits appendages, theslot in the shoe E allowing it to be raised, whilethe wheel J remains onthe groundeztnd supports the whole lower part of themachine. Thus thefinger-bar can be easily raised over obstructions wherever desired.

Having thus described myinventionfwhut I claim as new, and desire tosecure by Letters Patent, is`

-1. The 'frameA of a mowing-machine, when construetedof a. single bar,a,approximating in form yto a. horse-shoe, and o. transversestrengthening-bar, I), when theextremities of the bar a are bentdown forthe attachment of the shoe E, and Vii'rigerfbsi, substantially as hereinshown and described.

2. In combination with the above,v I claim the main wheel C, whenarranged betweenv the drivers sont and. the transverse bar b,substantially as and for the purpose set forth. f A.

3. The wheel J, on the hinged bar I, in combination witli'the slottedshoe E, and witlrthe lever.f, all made and operating so that thefinger-bar can be easily raised by means ofthe leverf, as set forth.
